Description

Technical Field

[0001] The utility model relates to a feeding device and injection molding mold equipment thereof. Background Art

[0002] Injection molding equipment is a collection of equipment and tools specifically used for the plastic injection molding process, including injection molding machines, molds, auxiliary equipment (such as cooling systems, automation devices, dust removal devices), temperature control equipment, and measurement and testing equipment. These devices work together to ensure that plastic materials are molded at appropriate temperature and pressure to produce high-quality plastic products.

[0003] Most of the existing small injection molding mold equipment is manual injection. The corresponding plastic fluid is added to the injection hopper, and then the swing arm is pressed down. The injection gun squeezes the material in the injection hopper downward and finally enters the mold at the bottom. It is molded by pressure. After molding, the product in the mold is taken out.

[0004] For the operator, the above process requires the following steps: putting in materials - pressing down the injection gun - entering the mold - pressing and molding - taking out the product. In particular, the process of putting in materials requires repeatedly adding plastic particles inside, which is relatively cumbersome and has low work efficiency. Utility Model Content

[0017] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0018] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-Figure 3 As shown, an injection molding mold 8 device includes a frame 1. A fixed frame 2 is provided on one side of the frame 1. An injection rod 3 is slidably provided on the fixed frame 2. A swing rod 4 is hinged on the top of the injection rod 3. A fixed rod 5 is hinged on the other end of the swing rod 4. The fixed rod 5 is fixedly connected to the fixed frame 2. A hopper 6 is provided on the fixed frame 2 corresponding to the injection rod 3. A heating device 7 is provided outside the hopper 6 for melting the plastic particles in the hopper 6. A mold 8 is provided at the bottom of the hopper 6, and an injection hole is provided on the mold 8 at a position corresponding to the bottom of the hopper 6, so that the melted plastic particles can be squeezed into the mold 8.

[0021] Correspondingly, the frame 1 is provided with a feeding device 9 for automatic feeding and a mold device 10 for facilitating the separation or close extrusion of the mold 8 so that the product can be formed and output.

[0022] 1. Feeding device 9

[0023] The feeding device 9 includes brackets 11 arranged on both sides of the top of the hopper 6 and fixedly connected to the hopper 6. Storage boxes 12 are slidably arranged on the brackets 11. A discharge hole 13 is arranged at the bottom of the storage box 12 for outputting plastic particles. When the storage box 12 moves to make the discharge hole 13 correspond to the top of the hopper 6, at this time, the plastic particles move out along the discharge hole 13 and enter the hopper 6, thereby achieving the purpose of convenient feeding.

[0024] A connecting rod 14 is hinged on one side of the storage box 12. A driving rod 15 is hinged on the connecting rod 14. A gear 16 is eccentrically connected to the driving rod 15. A driving shaft 17 is meshed in the middle of the two gears 16. The two gears 16 are located on both sides of the driving shaft 17. A connecting plate 18 is connected between the driving shaft 17 and the injection rod 3. When the injection rod 3 moves upward, the driving shaft 17 can be driven to move upward, so that the gear 16 meshed with the driving shaft 17 rotates. The rotation of the gear 16 drives the driving rod 15 and the connecting rod 14 to move, so that the storage box 12 slides back and forth on the bracket 11, and stops when the injection rod 3 leaves the hopper 6. At this time, the discharge hole 13 of the storage box 12 is placed above the hopper 6, and plastic particles are input into the hopper 6.

[0025] When the plastic particles enter the hopper 6 and gradually melt, the injection rod 3 moves downward, causing the injection rod 3 to drive the drive shaft 17 to move downward, thereby causing the two gears 16 to rotate in opposite directions, causing the storage box 12 to move back and forth on the bracket 11, and when the discharge hole 13 is placed above the hopper 6, a smaller number of plastic particles are fed into the hopper 6.

[0026] When the injection rod 3 gradually moves toward the hopper 6, the melted plastic fluid in the hopper 6 is pushed into the mold 8, and the plastic fluid in the mold 8 solidifies to form a product shape.

[0027] Optimally, an output shaft 19 is hinged at the bottom of one side of the swing arm 4, and the output shaft 19 is connected to a cylinder 20. The swing arm 4 is swung by the up and down push of the cylinder 20, thereby driving the injection rod 3 hinged to the swing arm 4 to move up and down.

[0028] Under the above settings, there is no need to manually add the corresponding plastic particle raw materials, and the purpose of automatic feeding is achieved. In addition, under the above settings, when the injection rod 3 moves up, the gear 16 rotates so that the storage box 12 reciprocates back and forth so that the discharge hole 13 at the bottom corresponds to the hopper 6, so that the plastic particles enter the hopper 6, and prevent too many plastic particles from entering at one time, causing the plastic particles to interact and become blocked. When the injection rod 3 moves down, the reciprocating storage box 12 will also add a small amount of plastic particles to the hopper 6 to reduce the feeding pressure when the injection rod 3 moves up.

[0029] It should be noted that the heating device 7 is located below the hopper 6 so that the plastic particles above the hopper 6 will not melt, thereby reducing the problem of the plastic particles adhering to the top of the hopper 6 after melting.

[0030] 2. Mold device 10

[0031] The mold device 10 includes a push frame 21 disposed on one side of the mold 8. Correspondingly, a slide groove 22 is also disposed at the bottom of the frame 1 for the push frame 21 to slide. A gear rod 23 is connected to one side of the push frame 21. The gear rod 23 is meshed with a gear 1 24, and the gear 1 24 is meshed with a gear 2 25. The gear 2 25 is meshed with a sliding rod 26. The sliding rod 26 is fixedly connected to one side of the drive shaft 17.

[0032] The mold 8 includes a fixed mold 27 and a sliding mold 28. The fixed mold 27 is fixedly arranged on the frame 1, and the sliding mold 28 is fixedly connected to the push frame 21. When the injection rod 3 moves downward, it can drive the drive shaft 17 to move downward, thereby driving the gear 2 25 to rotate counterclockwise and the gear 1 24 to rotate clockwise, and the gear 1 24 drives the gear rod 23 to slide, thereby driving the push frame 21 to slide. The push frame 21 drives the sliding mold 28 to slide on the frame 1 until it is tightly abutted against the fixed mold 27.

[0033] Furthermore, the thickness of the first gear tooth 24 is smaller than the thickness of the second gear tooth 25 , so that the gear rod 23 and the sliding rod 26 are arranged alternately.

[0034] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
